For these commands, the 34945EXT address is in the form:
1<
ext # ><00>
where:
ext # is the 34945EXT module and is a single digit in the range of 1 (master) to 2
(a 2nd (slave) 34945EXT in the L4491A). For example,
ROUT:RMOD:BANK:PRES 2,(@1200)
presets bank 2 on 34945EXT module 2.
Relay/Channel Relationship
The Keysight switches and attenuators listed in Table 1-2 are latching relays.
Therefore, there is a relay coil for each switch or attenuator position. In the
factory default configuration (
SYSTem:RMODule:RESet 1
), a distribution board
channel is assigned to each relay coil. There are 16 channels per distribution
board.
Channel Pairing
Channel numbers on the distribution boards are arranged to facilitate channel
pairing for dual-coil switches and attenuators. In paired configurations, channels
1-8 are paired with 11-18 (bank 1), 21-28 with 31-38 (bank 2), 41-48 with 51-58
(bank 3), and 61-68 with 71-78 (bank 4). Paired channels are controlled by a
single command (e.g.
OPEN
or
CLOSE
) in which only the lower channel of the
pair is specified. When a command (
OPEN
or
CLOSE
) is sent, the operation
sends a drive pulse to either the first or second channel in the pair - either
opening or closing the channel.
For the channel pair 1/11, the following syntax:
ROUT:CLOS (@1101)
- sends a drive pulse to the upper channel (1111)
ROUT:OPEN (@1101)
- sends a drive pulse to the lower channel (1101)
Non-Paired Channels
When channel pairing is not enabled (e.g. for single-coil drive), the channel
numbers within the bank are not consecutive. The range of the 16 channels
remains 1-8/11-18 (bank 1) ... 61-68/71-78 (bank 4). See the previous page.
